Application iiled February 18, 1896. Serial No. 579,776. (No model.)

To all `'whom it may] concern.:

Be it known that we,LAWRENGE MANUELL, of Newport, in the county of Newport and State of Rhode Island, and PLINY OATUCCI, of New York city, in the county and State of New York, have invented a new and lmproved Apparatus for the Utilization of Gan.

drawings, forming a part of this specification;

in which similar characters of yreference indicate corresponding parts in both the iigures.

Figure 1 is a partial side elevation and partial longitudinal vertical section through the apparatus employed for carrying ont the method, and Fig. 2 is a vertical .section through one of the members or cupsof the filtering-press shown in Fig. l.

A pit Ais constructed,into which the ma terial B to be treated is dumped, and a conveyer C is located partially Within the said pit and extending above the mouth of the same any desired distance. The said convcyer is illustrated as consisting of aloor and side boards 1l, while at the boot portion of the conveyor and at the upper end thereof a shaft 13 is suitably journaled, the-conveyer having any approved support at or near its two extremities. An endless belt 14 ispassed over suitable wheels or pulleys l2 and. 12a, located on the upper and lower shafts 13, and

the said belt is provided with plates 15, ,which4v stand atan angle to the bottom or bed 10 of the conveyor and take up the material from the aforesaid pit A, conducting it to the top portion of the conveyer, at which point the material is delivered-to a disi'ntegrator D, of any approved construction, in which machine the material is. thoroughly pulverize'd and is delivered through a nozzle 16jin a plastic or semifiuid state intoa pit 17, as shown in Fig. 1; This pit is provided 'witha suitable cover, and above the pit an elevator E is supported in any desirable manner, theeievator shownV comprising a casing 18, bifurcated at its lower.

Vaforesaid pit 17. The belt 21 passesthrough suitable openings in the-cover of the pit 17, and these openings are of sucient size to permit ofthe passage of buckets 22, secured on the said chain.

The buckets take Vthe disintegrated material and deliver the saine through a chute t at the top of the elevator-casing into a digester F. The digester isprovided with a .valve 27at its bottom, which, when open, will permit the entire contents of the digester to escape and fall into the pocket or the thirdv pit 28, (likewise shown in Fig. 1,) the material being received into the digester through an opening 29 at the top, which may be closed 'by a suitable cover.

At the base portion of the digester` above the valve 27 steam-pipes 30 are entered and likewise pipes 31,'connected with. a source of water-supply, and a suitablegage 32 is connected at the upper portion of the digester, while at rthe top of said digester a pipe 33 is attached, adapted to conduct grease from the digester, the said pipe having a suitable valve 34.-, and 'preferably where the greaseconducting pipe enters the digester a pipe 35 is tapped into the grease-conducting pipe, provided with a valve 35, and the said pipe is adapted to carry off any obnoxious gases that may be formed in the digester and convey the same toJ the iirebox of the boiler, for example, below the lire, or to any other point where said gases Will not contaminate the atmosphere. `The pipe 35 ,we preferably denominate a ,stink-pipe and the valve 35 a stink-valve. Y

The material delivered from the digester into the pit or pocket 28 will be in a liquid form, and the iiuid from the initial pit Ads yconducted through a pipe 36 into thedigestcr.-

IOO

,materiaL pit 28. 'I The liquid matter in the digester-pit is drawn therefrom through the medium of a pump 38, of any desired'construction, and is forced through a ilter-press G, inwhich the bulk of the material 'is retained for commer- .cial purposesfwhile the liqu id portion thereof,

after having been ilte'red, is delivered into a -pit or a chute'47, from whence it' may be conpress or those used for the separation of the clay from the water in which it may have been washed. The press comprises a series of disks.3 9, the intermediate disks having cupped faces and the outer end disks being cupped upon their inner faces only, and these disks are held closely together in horizontal arrangement against a, head 40, with which the discharge end of the pump 38 is connected by means of a screw and follower lil, mounted in a suitable frame. The cupped faces 42'of the parts of the filter-press receive and retain the solid 'matter contained vin the digested Communication is established between the various pockets 42 by forming openings43, preferably at the central portions of the disks. As illustrated in Fig. 2, iiltercloths, which may be .and preferably are of canvas, are placed upon the cupped or dished surfaces ofthe filter-press, the cloth being apertured at that point Where they would pass over the openingsa ijn' the disks. Drip valves 45 are connected with the pockets 42 and deliver the filtered liquid into a suitable receptacle 46, from whence the said liquid is conducted and delivered into the aforesaid chute 47.

In the operation ofthe apparatus, after the material is delivered into the digester, its ieceiv'ing-opening 29 is closed, likewise the lvalves 34 and 35, and Water is turned on in suitable, quantity through the pipes 3l, after which steam is admitted through the pipes 30, and the contents of the digester are boiled for a predeterminedv length of time, or until the greasehas been thoroughly separated from the aforesaid materiaL-and at any time when the gases in the digester accumulate in too great quantities, -as will be indicated by the gage, the stink-valve 35 is opened and the gasesl are permitted to escape and are conducted toa predetermined point. After the steam is turned oi from the digester the material contained therein is permitted' to settle and cool. The grease will rise tothe top, and

when this occurs the water is again admitted l tothe digester. l. The valve 34 in the greaseconducting pipe should now be opened,l and the grease is floated up int-o the aforesaid pipe.

The digester having been practically freed from grease, the lower valve? is opened, and

the contents of the digesterjare emptied into the pit 28 by the above-described operation. The digested material is caused to assume a semiuid or thickened-liquid-like form. Fnom Vthe pit 28 and by means of the pump 3S the digested material is forced through they filter-press and the liquid separated from the ymore solid elements of the mixture.

These solid substances are retained in thev press,

Having thu'sdescribedour invention, we

claim as new and'desire to secure by Letters An apparatus for treating garbage, the ap'- paratus having a pit, a con veyer leading from the pit, a disintegrator to whichthe conveyer feeds, the disintegrator emptying into asecond pit, an elevator rising' fromthe second pit,a casing inclosing the elevator, a digester to which'the elevator extends, a third" pit in which the4 digester empties, a pump commu. nicating with the third pit, and a iilte'r fed by 1the pump, substantially as described.
